03D587ACF65BFFA8189F40B6FB1CFB70.taxon	discussion	Remarks. I include this species in the nivosa group. The original description (Makarchenko 1983) did not contain data on the shape and structure of the transverse sternapodeme. Namely, these characters are present only in P. (s. str.) gorodkovi and are absent in other representatives of the genus. Also, this species differs from the known members of Pseudodiamesa by a short massive gonostylus with a large lobe along the outer edge and some other features specified in this redescription.	en	Makarchenko, Eugenyi A.

I include this species in the nivosa group. In the original description (Makarchenko 1984), a mistake was made in indicating the terminal spine on the gonostylus. An analysis of the gonostylus of all available specimens showed that one of the setae near the apex was taken as a short terminal spine. Also, there was no information on the shape and structure of the transverse sternapodeme and there were inaccuracies in the number of setae and measurements of some parts of the male adult. P. (s. str.) venusta differs from other members of the genus mainly in the structure of the hypopygium, namely in the shape of the gonostylus which is wide in the basal part and finger-shaped in the distal part, as well as in the shape and structure of the gonocoxite, the anal point, and other features given in the redescription.	en	Makarchenko, Eugenyi A.
